专利号:US-11773128-B2 优先权日:2019-03-28 标题 :Electrocatalytic synthesis of dihydrochalcones 发明人:REDKO MIKHAIL; SAFFRON CHRISTOPHER M; JACKSON JAMES E 权利人:UNIV MICHIGAN STATE 摘要:The disclosure relates to methods of forming a dihydrochalcone using electrocatalytic dehydrogenation. In particular, the disclosure relates to methods of forming a dihydrochalcone electrocatalytically hydrogenating (ECH) a reactant compound over a catalytic cathode in a reaction medium having a non-alkaline pH value, thereby forming a dihydrochalcone product; wherein the reactant compound has a structure according to Formula (I). The method can be used to prepare dihydrochalcone sweeteners, such as, for example, naringin dihydrochalcone and neohesperidin dihydrochalcone.
专利号:US-2007232495-A1 优先权日:2006-03-24 标题:Compositions and methods to add value to plant products, increasing the commercial quality, resistance to external factors and polyphenol content thereof 发明人:NAPPA ALVARO O; LORENZINI FELIPE C; SANHUEZA ANDRES L 权利人:NAPPA ALVARO O; LORENZINI FELIPE C; SANHUEZA ANDRES L 摘要:The invention is related to compositions and methods that naturally protect plant tissues against ultraviolet radiation and temperature, thus giving protection against sunburn to plants, plant parts, fruits and/or flowers during their development. The invention is also related to compositions and methods to naturally improve the color of plants, plant parts, fruits and/or flowers by inducing the natural synthesis of flavonoids and anthocyanins present in plants. Likewise, the present invention is directed to improving the nutritional value of plants, plant parts, fruits and/or flowers by increasing the normal levels of polyphenolic compounds, especially flavonoids, present therein. Additionally, the present invention is related to compositions and methods that give more resistance to plants, plant parts, fruits and/or flowers against pathogens as bacteria and fungi. Finally, the present invention is related to plants, plant parts, fruits, flowers and/or propagating material treated with the compositions described in the present document.
